EDIT: be aware that the links to Facebook and Twitter go to the home pages of each site, rather than to your account page on each site, so grab the actual url of your accounts in each case, or following these links will be a waste of time for your visitors.

I did that, just now, and the RSS icon is still there, but the facebook and twitter icons are nowhere to be found. This is kind of tricky...that is all I could get to happen in my tinkering so far, also.
